Tesla S Owner's Manual page 239

◦ In extremely cold climates, this alert
may remain present indefinitely and
regenerative braking may remain
reduced, as driving the vehicle may
not warm the battery enough to fully
restore performance.
Typically, driving will clear this alert because
it will reduce the battery charge level below
95% and sufficiently warm the battery.
This is a completely normal part of vehicle
operation and should not cause alarm. The
notice on the screen is for your information
only.
For more information on regenerative
braking, see the Regenerative Braking section
in the Owner's Manual.

Powertrain requires service
Avoid hard acceleration
An issue has been detected in the powertrain
system. The vehicle is OK to drive, but you
should schedule service as soon as possible
for a powertrain inspection.
Your vehicle has detected excessive backlash
(lash) between the drive unit and the wheels.
High, or excessive, lash is indicative of
mechanical wear.
There are many possible causes, so a
powertrain inspection is needed.
Your vehicle is OK to drive to your immediate
destination and to a service center. Avoid
hard or heavy acceleration, as this puts more
stress on the powertrain.
Schedule a service appointment at your
earliest opportunity. If this issue is not
addressed, your vehicle might unexpectedly
stop while you are driving.

Assist for low brake
performance activated
To stop, keep brake pedal
firmly pressed
Hydraulic Fade Compensation is active. This
brake assist function activates temporarily to
make sure you have full braking capability in
conditions where reduced braking
performance is detected by your vehicle.
Continue to press the brake pedal as you
normally would, and do not "pump"
(repeatedly press and release) the pedal as
this will interrupt the function.
This alert will clear when your vehicle comes
to a stop or you are no longer pressing the
brake pedal. It may still be displayed for up to
5 seconds afterward.
When this assist function activates, you may
feel the brake pedal pull away from your foot
and notice a strong increase in brake
pressure. You may also hear a pumping sound
coming from the brake hydraulic unit at the
front of the vehicle. This will usually last for a
few seconds, depending on road surface and
vehicle speed. This is completely normal and
does not indicate any issue with your vehicle.
Reduced braking performance is usually
temporary, and can occur for a number of
reasons including high brake temperatures
after heavy brake use, or driving in extremely
cold or wet conditions. It can also indicate
that your brake pads or rotors have worn to
the point that normal replacement is needed.
If you continue to experience reduced braking
performance which does not improve over
time, please contact Tesla service at your
convenience for a brake inspection.
